Dao v The Queen

The case of Dao v The Queen involves an appeal against sentencing by the appellant, who was convicted of trafficking in large commercial quantities of drugs, specifically heroin and methyl amphetamine, on a single day. The appellant was sentenced to a total effective term of 18 years with a non-parole period of 13 years. The appeal centred on whether this sentence was manifestly excessive, given the nature and extent of the offence, and the appellant's role within the criminal hierarchy.

The primary legal issues before the court were whether the sentence imposed was excessively harsh considering the appellant's limited role in the drug trafficking operation, the sufficiency of evidence to substantiate the appellant's role, and whether the offence deserved characterisation as the most serious example of the most serious offence. The court was also required to consider if the principles set out in Verdins applied and if the sentence could be considered 'crushing' under the circumstances.

The court determined that the sentence was not manifestly excessive. It found that the appellant's role, although described as limited, was not definitively proven to be as minor as claimed. The court also held that the offence was correctly characterised as the most serious example of the most serious offence due to the vast quantity of drugs involved, more than 30 times the large commercial quantity. The Verdins principles were not considered applicable in this instance. The court concluded that the sentence, while severe, was proportionate to the gravity of the offence and the appellant's role in it.

The appeals were dismissed, and the original sentence was upheld. The court referred to several precedents, including Wong v The Queen, Mokbel v The Queen, Rizzo v The Queen, Kumova v The Queen, Gonzales v The Queen, and R v Vaitos, to support its decision. The final orders confirmed the maintenance of the original sentence, with the non-parole period remaining at 13 years.
